Update build-image.sh feat(script): add create-recovery-disk.sh to build macOS recovery image for QEMU/Proxmox
- Added script to automate creation of a macOS recovery disk image compatible with QEMU - Generates a sparse disk, partitions it, and prepares a minimal recovery volume - Copies BaseSystem.dmg and optional .chunklist into the recovery partition - Converts resulting DMG to a raw image for direct use in Proxmox VE VMs - Includes cleanup routines and device mount management via diskutil/hdiutil - Requires: macOS with hdiutil, diskutil, and qemu-img installed
